Hotpoint Mistral Plus
My good freind David asks me if I can look at his fridge, I do not usually attend to domestics, but since I look after all his other stuff at the restaurant, I dont wish to upset him......
Its a Hotpoint Mistral Plus............the evaporator fan does not work, or run.........
I wait for the coil to decrease in temperature, which it does, down to -8C, but still the fan wont run.
I think the fan kicks in when the evaporator reaches a certain temperature.
I think it is a faulty thermistor............Does any member have experience of this fault ??
According to him, the freezer section was down to temp, the fridge section was not..........
And if it is the thermistor...........where can I grab hold of a spare part ??
Thx in advance
Chez

Re: Hotpoint Mistral Plus
Aiyub generaly the fan is delayed by using the defrost heater as a neutral. This fault is generally caused by either the defrost termination tstat being open circuit and not resetting (often klixon button type attached to evap.) The other commen cause is the defrost heater burnt out. I assume the fan itself meters out ok . I think im in Coventry

Re: Hotpoint Mistral Plus
Hi Abe,
The way Coolkev described it is 95% of no frost fridges,
I always say, follow the -0- and you find the problem.
Today, the suckers don't use all these component, you see the fan and defrost heater and thats it, at the back under a cover, is an electronic controller that controls the whole unit, defrost comes on only after you open the freezer door for so many times and they consume less then half electricity.
The problem - to change this card, costs like half the fridge.

Re: Hotpoint Mistral Plus
I used to do domestics and had to repair many of these stupid things, they are a royal pain in the bum.
It will most likely be the evap thermister but watch out for the door switch.
I used to take a quick look around the fridge and change the thermister if all else seemed ok.
If you watch the fan and see if it starts ....runs for a few secs and then stops again this is telling you there is a problem with the fan because on the pcb there is a cut out (looks like a little blue blob on legs).
Check the fan for a small crack in the plastic round the windings .
If the fan looks like its nacked watch out if you are buying a new motor. On some models you have to change the pcb as well because the new motor needs a differant cut out. (hotpoint changed the motors and you can`t get an old rated one).
Or you could do what I used to do and bypass the cut out when you get the new motor.
Don`t try phoning hotpoint as they are not much help. You really shouldn`t have started working on this, they are a nightmare lets hope it`s the thermister and you dont get called back.
Can`t remember where we used to get our parts i think it was electrue part or somthing like thatLast edited by chillin out; 05-12-2004 at 06:19 PM. Reason: spelling

Re: Hotpoint Mistral Plus
Hi Chillin
You are right..............At start up the fan spins just for a wee before stopping completely.
It is Definately not the Door switch..........It may be the thermister or the pcb as you said...........
As you say it is a right royal pain..........Ive already been out twice to this thing, and still not resolved.
And you guys thought domestics were a piece of piss ??? Ha haaaaa
Im waving the white flag, let a Hotpoint factory trained bod deal with this.............
Trouble is customers want to save a few bob and get me in to have a look at it, you know who loses??? Yes sirree , it is I, I end up looking like I dont know anything , in the eyes of the customer.
Moral is, steer clear of this flaming Hotpoints..........Any opinions, statements and facts expressed in this message do not constitute legal advice in any shape or form and is given for a general outlook in nature.
